Etymology[edit]

From Old Irish secht, from Proto-Celtic *sextam, from Proto-Indo-European *septḿ̥.

Pronunciation[edit]

Numeral[edit]

seacht (triggers eclipsis)

  1. seven

Usage notes[edit]

  • May be used with nouns in both the singular and plural; the singular is more common in general, but the plural must be used with units of measurement and the like. Triggers eclipsis:
  • seacht gcatseven cats
  • seacht dtroitheseven feet
  • seacht n-uaireseven times
  • When used with the definite article, the definite article is always in the plural. When used with nouns modified by adjectives, the adjective is also in the plural and is always lenited after nouns in the singular but only lenites after nouns in the plural when they end in slender consonants:
  • seacht gcapall bhánaseven white horses
  • na seacht n-eaglais mhórathe seven big churches
But:
  • seacht gcapaill bhánaseven white horses
  • na seacht n-eaglaisí mórathe seven big churches
